Description

BACKGROUND Area of ​​Revelation

[0001] The present disclosure relates in general to a bicycle control device and more specifically to a bicycle control device comprising a brake lever and an electronic gear shift control system for mounting on the handlebars of a bicycle. GENERAL STATE OF THE ART

[0002] For a typical electronic gear shifter for a bicycle, the battery unit for the gear shifting system and the sockets for connecting remote gear shift buttons are combined in a single printed circuit board assembly. This increases costs and limits the placement options for these components on the device.

[0003] The battery is housed in a compartment within the battery unit, which is closed by a battery cover. The battery cover is attached to the unit using several small screw fasteners. These small fasteners can make removing and reinstalling the battery cover difficult. As a result, a user or driver must have the correct tools readily available each time the battery needs to be removed and replaced.

[0004] Furthermore, remote connector sockets for connecting remote gearshift control buttons are typically not sealed against the ingress of water or other contaminants unless a separate plug is installed. Without a plug in the sockets, water and other contaminants can enter and reach the battery circuit board assembly, then travel through the electrical wiring to the gearshift button circuit board assembly. These components can be damaged if exposed to water and other contaminants.

[0005] The battery unit is typically not sealed against the ingress of water or contaminants unless the battery cover gasket is installed. In some cases, the battery cover may be compromised, allowing water or other contaminants to enter even if the cover is present. Without a proper battery cover gasket, water and other contaminants can enter the battery unit, reach the battery's printed circuit board assembly, and travel through the electrical wiring to the gearshift button assembly. These components can then be damaged if exposed to water and other contaminants.

[0006] Furthermore, an electrical cable typically connects the circuit board assembly of the gear shift buttons to the battery and the circuit board assembly of the remote gear shift button jacks. The cable passes through the center of the cover or housing of the bicycle control device. Thus, either the cable must be connected after it has been routed through the device's cover, or the cover must be notched to accommodate the cable. Adding a notch to the cover compromises its strength. Connecting the cable after it has been routed through the cover can also be problematic. This is because the bicycle control device must be designed and tested independently of the brake control assembly, which is part of the device.

[0007] A grommet is also typically used at the interface between the electrical cable and the circuit board of the gear shift control unit in the gear shift lever. This means that the multi-pin connector used to secure the cable to the circuit board must be installed after the cable has been fed through the grommet. This can complicate the assembly of the bicycle control unit.

[0008] DE 10 2015 003 775 A1 discloses a control arrangement for a bicycle for controlling an electromechanical switching device. The arrangement includes a housing that can be attached to a bicycle handlebar by means of a bracket. A brake lever and a shift lever are arranged on the housing, each pivotable about an axis relative to the housing. The two axes are arranged orthogonally to each other. Inside the housing, a power supply in the form of a button cell is arranged in a holder, which can be closed off to the outside by means of a screw-on housing cover. The housing cover is located on the side of the housing, and the button cell is thus accessible by removing the side housing cover.

[0009] Another control device for a bicycle with a battery in a battery container is known from DE 10 2017 007 568 A1.

[0010] Another control arrangement is known from DE 10 2007 005 120 A1.

[0011] It is an object of the invention to provide a control device that overcomes at least one of the aforementioned disadvantages of the prior art. SUMMARY

[0012] The invention relates to a control device according to claim 1. Furthermore, the invention relates to a control device according to claim 19. The dependent claims relate to advantageous embodiments of the invention.

[0013] A bicycle control device comprising a brake lever and an electronic gearshift control system is disclosed herein. The control device is mounted to the handlebars of a bicycle via a main cover or housing that includes a bracket and creates or defines a grip. In one example, the brake control of the device is intended for a hydraulic brake system. However, the disclosed bicycle control device can instead be configured to use a mechanical cable brake system. The electronic gearshift control system of the device has a primary actuation button located next to the brake lever. The electronic gearshift control system is also configured to wirelessly transmit gearshift signals, includes a battery unit, and comprises inputs or jacks for connecting to remote gearshift control buttons located elsewhere on the bicycle.

[0014] In an example according to the teachings of the present disclosure, a control device can be mounted on a bicycle handlebar. The control device comprises a housing sized and designed to be grasped by a user's hand, a gearshift lever coupled to and movable relative to the housing, an electrical switch that can be actuated by a movement of the gearshift lever, and a controller connected to the electrical switch. The controller is configured to generate a signal in response to the actuation of the electrical switch. The control device also comprises a communication module configured to transmit the signal, a battery compartment on part of the housing, and a removable battery cover that seals the battery compartment.The battery housing is configured to contain a battery to power the controller and communication module. The housing has a base section and an extension section. The base section comprises first and second ends, a downward-facing side, an upward-facing side, an inward-facing side, an outward-facing side, and a handlebar clamp located at the first end. When the control device is mounted on a bicycle handlebar, the base section generally extends horizontally, and the extension section extends in front of the base section at the second end, generally angled upward from the base section. The battery housing terminates on the downward-facing side of the base section.

[0015] For example, the battery cover can be rotatable so that it can be removed from and installed on the battery container.

[0016] For example, the battery cover can be circular and can include a seal, such as an O-ring, around its circumference.

[0017] For example, the battery container can be provided in a battery box that can be accommodated in a recess in the base section of the housing and that can be attached or secured to the housing.

[0018] For example, the battery cover of a battery box attached to the housing can be removable and reinstalled.

[0019] For example, the battery cover can be removable to access the battery compartment and can be removed and installed without the use of tools.

[0020] In one example, the battery cover and battery box can be provided as part of a gearshift assembly that also includes the gearshift lever. The battery box can be connected to the gearshift lever by an electrical cable.

[0021] In one example, the control device may include one or more accessory sockets that are accessible on a side of the base section of the housing other than the downward-facing side.

[0022] In one example, the control device may include one or more accessory sockets that are accessible either on the inward-facing side or on the outward-facing side of the base section of the housing.

[0023] In one example, the control device may include a brake lever that can be pivotally mounted on the housing and is operational to actuate a bicycle's braking system.

[0024] In one example, the gearshift lever can be part of a gearshift lever assembly mounted on a brake lever of the control device. The gearshift lever can pivot together with the brake lever about a brake pivot axis and can also be movable laterally independently of the brake lever about a gearshift lever pivot axis that is perpendicular or otherwise oriented to the brake lever pivot axis.

[0025] In one example, the control device may include a controller that can be configured to generate a signal to change a gear shift position of a bicycle's gear shifting mechanism in response to the actuation of an electrical switch.

[0026] In one example, the controller can be configured to generate a high-frequency signal to change the gear position of a bicycle's gearshift mechanism in response to the actuation of an electrical switch. An antenna can be in high-frequency communication with the controller to transmit the high-frequency signal.

[0027] In one example, the control device may include an electrical switch, a controller, and an antenna, each of which may be part of a gearshift lever assembly and may be mounted on a section of the gearshift lever.

[0028] In one example, the control device may comprise a gearshift lever assembly, which further comprises a printed circuit board that is mounted in a section of the gearshift lever. An electrical switch, a controller, and an antenna may each be mounted, at least partially, on a printed circuit board inside the gearshift lever.

[0029] In one example, the battery container can be provided within a battery box, which is received in a recess in the base section of the housing. The battery box can include a second cavity located opposite the battery container on the side of the battery box. This second cavity can be oriented towards a recess in the housing.

[0030] In one example, the control device may further comprise a positive contact with a contact section exposed inside the battery container and a connecting piece section exposed inside the second cavity; a negative contact with a contact section exposed inside the battery container and a connecting piece section exposed inside the second cavity; and electrical wires connected to the connecting pieces of the first and second contacts exposed inside the second cavity. The second cavity may be filled with an epoxy material that can cover the electrical wires and the connecting pieces of the first and second contacts.

[0031] For example, the communication module could be a wireless communication module configured to transmit the signal wirelessly.

[0032] In an example according to the teachings of the present disclosure, a control device for a bicycle comprises a housing that is mountable on the bicycle and is dimensioned and designed to be grasped by a user's hand, a battery container positioned on the housing, and at least one accessory socket accessible on an outside of the housing. The at least one accessory socket is configured to receive an electrical connector of a remote accessory located spaced apart from the control device on the bicycle. The housing has a base section and an extension section. The base section comprises first and second ends, a downward-facing side, an upward-facing side, an inward-facing side, an outward-facing side, and a handlebar clamp located at the first end.When the control unit is mounted on the bicycle handlebars, the base section generally extends horizontally, and the extension section extends in front of the base section at the other end, generally angled upwards from the base section. The battery compartment is positioned on a first side, selected from the downward, upward, inward, and outward-facing sides of the base section of the housing. The at least one accessory socket is positioned on a second side, different from the first side, also selected from the downward, upward, inward, and outward-facing sides of the base section of the housing.

[0033] In one example, the control device may include a gearshift lever assembly attached to the housing. The gearshift lever assembly may include a battery box attached to the front side of the housing. The battery compartment may be defined inside the battery box and may open onto the exterior of the housing. A gearshift lever may be coupled to the housing and movable relative to it. The movement of the gearshift lever may actuate an electrical switch. A controller may communicate wirelessly with the electrical switch and may be connected to the battery box by a first electrical wire. The one or more accessory sockets may be connected to the controller by a second electrical wire.

[0034] In one example, the enclosure can be configured to provide a first conductor channel through which a first electrical wire is routed from a controller to the location of the battery container, and to provide a second conductor channel through which a second electrical wire is routed from the controller to the location of the at least one accessory socket.

[0035] In one example, the control device can include a brake lever that is pivotally connected to the housing and is movable relative to it.

[0036] In one example, the control device may include a gearshift lever assembly with a gearshift lever that may be mounted on the brake lever. The gearshift lever may pivot together with the brake lever about a brake pivot axis and may be movable laterally independently of the brake lever about a gearshift lever pivot axis that is different from the brake lever pivot axis.

[0037] In one example, the control device may include a gearshift lever assembly, which may include a printed circuit board housed inside a cavity in a rocker end of a gearshift lever.

[0038] In one example, the at least one accessory socket can comprise multiple accessory sockets. Each of these multiple accessory sockets can be connected to a controller of a gearshift lever assembly by a corresponding multiple of secondary electrical wires.

[0039] In one example, the control device may include a controller that can be configured to generate a signal to change a gear shift position of a bicycle's gear shifting mechanism in response to the actuation of an electrical switch.

[0040] For example, the battery compartment can be positioned on the downward-facing side of the base section of the housing.

[0041] For example, the at least one accessory socket can be positioned on the inward-facing side or the outward-facing side of the base section of the housing.

[0042] In an example according to the teachings of the present disclosure, a control device is configured for actuating an electromechanical gearshift mechanism of a bicycle. The control device comprises a housing that can be mounted on a bicycle and a brake lever that is coupled to the housing and pivotally movable relative to it. The brake lever has a contact surface on a portion thereof, a gearshift lever that is movable together with the brake lever and is movable relative to the housing and the brake lever, and a base plate that is provided on a receiving section of the gearshift lever. The contact surface of the brake lever is arranged in contact with the base plate.

[0043] In one example, the recording section could be a recess provided on the gearshift lever.

[0044] For example, the base plate can be fitted into a recess on the gearshift lever and can have a friction-reducing surface that is exposed to and thus in contact with the contact surface of the brake lever.

[0045] In one example, the base plate can be fitted into a recess on the gearshift lever.

[0046] In one example, the base plate can be clamped between the contact surface of the brake lever and the receiving section on the gearshift lever.

[0047] In one example, the base plate can be made of a different material than the gearshift lever and be attached to the gearshift lever.

[0048] In one example, the base plate can be made of a Teflon material. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] A bicycle control device is disclosed herein that addresses or mitigates one or more of the aforementioned and / or other problems and disadvantages of previously known control devices. The disclosed bicycle control device comprises a brake lever and an electronic gear shift control system. The control device is mounted on the handlebars of a bicycle. The brake control of the device can be designed to actuate a hydraulic brake system or a mechanical cable brake system. The electronic gear shift control system of the device is also configured to transmit gear shift signals wirelessly, includes a battery unit, and comprises accessory connectors or sockets for connecting to remote gear shift controls or buttons located elsewhere on the bicycle.The accessory ports can be configured as input ports to receive input signals from the remote gearshift control devices.

[0051] The person skilled in the art will understand that the drawings and detailed description provided here serve only for illustrative purposes and do not limit the scope of the invention or the disclosure. The accompanying claims define the scope of the invention and the disclosure. The terms "first," "second," and the like, as well as "front," "rear," "left," "right," and the like, are used for convenience only. These and similar terms are not used here as limiting terms. Furthermore, these terms refer to bicycle mechanisms conventionally mounted on a bicycle, wherein the bicycle is oriented and used in a standard manner, unless otherwise specified.

[0052] Now, with reference to the drawings, it is stated Fig. Figure 1 shows a bicycle 50 with a frame 52, a front wheel 54 coupled to a fork 56 of the frame, and a rear wheel 58 coupled to the rear forks 60 and rear forks 62 of the frame. The wheels 54 and 58 support the frame 52 on a surface on which the bicycle 50 can travel in a forward direction indicated by arrow A. The bicycle 50 has a handlebar 64 of the type of racing handlebar, which is mounted on a steering stem 66 of the frame 52. The bicycle 50 also has a saddle 68, which is supported by a seat post 70 that is received in a seat tube 72 of the frame 50. The bicycle 50 may have one or both of a front derailleur 74 and a rear derailleur 76, which are mounted on the frame 52. Gearboxes 74 and 76, for example, can be electromechanical derailleur gears.The bicycle 50 comprises a multi-stage drive system 78 with one or more chainrings 80, which is / are driven by a crank assembly 82, each having two crank arms 84 and two pedals 86. The chainrings 80 can be connected by a chain 90 to a plurality of sprockets 88 on the rear wheel 58. The bicycle 50 as described above is known in engineering.

[0053] With reference to Fig. In the disclosed example 1 to 5, the bicycle 50 has at least one bicycle steering device 100, hereinafter referred to as the “steering device 100”, which may be mounted on the handlebar 64. In this example, the steering device 100 comprises a brake control element of a braking system. The brake control element comprises a brake lever 102, which is movably connected to a cover or housing 104 of the device. The brake lever 102 actuates the components of the braking system of the bicycle 50. In one example, the braking system may comprise one or both of a hydraulic front brake mechanism 106, which is coupled to the front wheel 54, and a hydraulic rear brake mechanism 108, which is coupled to the rear wheel via hydraulic lines 110. As noted previously, the braking system may instead be a mechanical cable brake system.As described in more detail below, the control device 100 also includes a gearshift control element of an electronic gearshift control system. The gearshift control element comprises a gearshift lever assembly 112 for shifting the gears of the bicycle 50.

[0054] With reference to Fig. Figures 2 to 6 show various external views of the control device 100, which is constructed according to an example of the present disclosure. The control device 100 can be mounted on the handlebar 64. In one example, the housing 104 can accommodate and include a clamp 120 of a known type, which may be or include an adjustable band extending around the handlebar. In another example, the bicycle 50 can include a pair of control devices 100, one on each side of the handlebar 64, as is well known. The person skilled in the art will understand that the pair of control devices 100 can be configured together to actuate the respective front and rear electromechanical derailleurs 74, 76 and the respective front and rear brake mechanisms 106, 108. In another example, the pair of control devices 100 can be identical.

[0055] In the disclosed example, the control device comprises 100 with reference to Fig. 6 to 8 a cover, i.e., the housing 104, which may be covered by an external or outer cover 122. The housing 104 is designed and sized to be grasped by the hand of a user or driver, and the outer cover 122 may be configured to closely follow and overlap the shape of the housing. The housing 104 and the outer cover 122 may serve as a handle or may be configured together as a grippable section of the control device 100. The housing 104 may be formed from any suitable material, such as metal, plastic, and / or composite materials. The housing 100 is designed to carry, accommodate, and / or support the various components and mechanisms of the brake system controls and the electronic gearshift control system, as described in more detail below.The outer cover 122 can be made of any suitable material, such as natural and / or synthetic elastomeric materials, and can be designed to provide a comfortable user interface and to reduce the tendency to detach or be removed from its position on the exterior of the housing 100. For example, the outer cover 122 can be formed from a flexible thermoplastic elastomer (TPE), such as Santoprene™. The outer cover 122 can be configured to be detachably attached to and held in position on the housing 104 using any known securing and fastening method.

[0056] In this example, with reference to Fig. Figures 7 to 9, in which the outer cover 122 has been removed, show the brake lever 102 pivotally or movably mounted on the housing 104. The brake lever 102 can be mounted on the housing 104 at or near the conductive or front part of the housing such that the brake lever is spaced forward from the handlebar 64. The brake lever 102 can thus pivot relative to the housing 104, generally forward and backward. The brake lever 102 can also be made of any suitable material, such as metal, plastic, or composite materials. The brake lever 102 can include a pivot bore or holes 124 near its proximal end. The pivot holes 124 can be aligned with each other and define a pivot axis P, which is generally oriented perpendicular to the longitudinal axis of a handle 125 of the brake lever 102.The brake lever 102 can be attached to the housing 100 by means of an axle 126, which may be in the form of a pivot pin, a rod, a shaft or the like, through the holes 124.

[0057] In the disclosed example, with reference to Fig. 2. The brake lever 102 has a U-shaped recess or defines a channel 128 along at least one longitudinal section of the handlebar grip 125. The gearshift lever assembly 112 can be positioned at least partially inside the recess or channel 128 in a nested arrangement, as described in more detail below. This nested arrangement of the gearshift lever assembly 112 with the brake lever 102 and the U-shape of the lever body can impart some rigidity to the structure and can provide protection for the components located inside the channel. The gearshift lever assembly 112 can also be pivotally or movably attached to the housing 100, to a pivoting mechanism, or to the brake lever 102. The gearshift lever assembly 112 can be positioned behind the brake lever 102, i.e., between the brake lever and the handlebar 64, when installed on the bicycle 50.The gearshift lever assembly 112 can also be manufactured from any suitable material, such as plastic or composite materials. For example, the gearshift lever assembly 112 should be manufactured at least partially from a material that does not substantially impede wirelessly transmitted signals from penetrating the material.

[0058] Fig. 9 and Fig. Figure 10 shows cross-sections of the brake lever 102 and the gearshift lever assembly 112 in an assembled or operating arrangement. With reference to Fig. 2, Fig. 9 and Fig. The channel of the brake lever 102 is defined by spaced-apart side walls comprising an inner wall 130a and an outer wall 130b with respect to the orientation of the bicycle 50, and within a forward-facing wall 130c. The gearshift lever assembly is nested within the channel 128. As described in more detail below, the gearshift lever assembly 112 can pivot laterally about the axis 126 in one direction between the side walls 130a, 130b about an axis S that is generally perpendicular to the pivot axis P of the brake lever 102. Thus, the gearshift lever assembly 112 can move in the inner and outer directions with respect to the bicycle 50 while remaining nested and aligned with the brake lever 102.

[0059] In general, the gearshift lever assembly 112 has the following characteristics with regard to Fig. Figures 9 to 11 show a gearshift lever 132 comprising a proximal end 134 that is pivotally attached, directly or indirectly, to the housing 104 or the brake lever 102 by means of a pivot pin 136 that defines the pivot axis S of the gearshift lever assembly. The gearshift lever 132 also has a distal or rocker end 138 opposite the proximal end and an elongated lever arm 140 connecting the proximal and distal ends. The lever arm 140 may be a closed hollow body or may be U-shaped or open-sided and include structural ribs therein.

[0060] In one example, the proximal end 134 of the gearshift lever 132 may also have a transverse opening 142 positioned to accommodate the pivot axis 126 of the brake lever 102, which passes through the gearshift lever assembly 112. The proximal end 134 of the gearshift lever 132 may also carry connecting components (not described in detail here) for connecting the brake lever 102 to the hydraulic brake system. These components may include a sleeve 144, which is supported by the gearshift lever 132 and spaced apart from and parallel to the transverse opening 142. When the gearshift lever assembly 112 is assembled with the brake lever 102, the sleeve is received in a set of openings 145 at the proximal end of the brake lever 102, spaced apart from the pivot bore 124.The combination of the sleeve 144 and the openings 145, together with the transverse opening 142 and the axis 126, pairs the brake lever 102 and the gearshift lever assembly 112 with respect to the brake lever pivot axis P. The gearshift lever assembly 112 is thus configured to move around the pivot axis P together with the brake lever 102 when the braking system is actuated, but moves independently of the brake lever when the gearshift control system is actuated. As described in more detail below, the rocker end 138 of the gearshift lever 132 includes an internal cavity 146 that houses electronic components of the gearshift lever assembly 112 and the gearshift control system.

[0061] With reference to Fig. 11 and Fig. 12 The bicycle control device 100 has four primary parts, which are the housing 104, the outer cover 122 (not shown, see Fig. 6), comprising the brake lever 102 and the gearshift lever assembly 112. The gearshift lever assembly 112 and the housing 104 each further comprise additional auxiliary components according to the teachings of the present invention and as generally described in Fig. 12 are shown.

[0062] In the disclosed example with reference to Fig. In Figures 11 to 14, the gearshift lever assembly 112 is a self-contained electrical assembly which, as described below, offers several advantages and improvements over previously known bicycle control devices of this type. In this example, the gearshift lever assembly 112 comprises electronic component sets for actuating the bicycle control device 100. Some of the electronic component sets in this example are located inside the inner cavity 146 in the rocker end 138 of the gearshift lever 132, and some of the component sets are externally but electrically connected to the component sets inside the cavity.

[0063] In this example, the rocker end 138 of the gearshift lever 132 has a larger surface area than the adjacent lever arm 140. The rocker end 138 thus provides a practical and ergonomic contact point for the user. The inner cavity 146 includes a cover 148, which can be secured to the rocker end 138 by connecting elements 150 to close the cavity and prevent the ingress of water and other contaminants. A seal 152 can be inserted between the inner cavity 146 and the cover 148. The seal 152 can be a sealing membrane or a layer of rubber or any suitable material that satisfactorily seals the cavity 146 to prevent the ingress of moisture or contaminants.

[0064] In one example, a printed circuit board (PCB) 154 is arranged inside the sealed cavity 146. Various electronic component sets can be mounted on or connected to the PCB 154. The PCB 154 can include a communication module 156 configured to transmit signals from the control device 100. In one example, the communication module 156 can be configured to wirelessly transmit signals in the form of electromagnetic radiation (EMR), such as radio waves or high-frequency signals. Optionally, the communication module 156 can also be configured to receive signals. In one example, the communication module 156 can be configured to receive signals that may be in the form of EMR, such as radio waves or high-frequency signals. The communication module 156 can include or be a transmitter or a transceiver.The PCB 154 can also include an antenna 158, which is in operational communication with the communication module 156 to transmit and optionally also receive EMR signals. The antenna 158 can be any device designed to transmit and / or receive electromagnetic radiation (e.g., television or radio) waves.

[0065] In the disclosed example, the antenna 158 is located on the PCB 154 in a position that enables it to transmit signals without significant interference from the structure of the bicycle control device 100 and / or from a user's hand. In another example, the antenna 158 can be a wireless antenna to help reduce or prevent interference and can be positioned at least partially in or on a section of the bicycle control device 100 that is separate and spaced away from the housing 104. For example, the antenna 158 can be positioned on another part of the brake lever 102 or the gearshift lever 132.

[0066] The bicycle control device 100 also includes a controller 160, which in this example is also located on PCB 154. The controller 160 is operationally connected to the communication module 156 to perform electronic operations, such as generating signals for one or more gear shifts, couplings, derailleur adjustments, energy management, and the like. The controller 160 can be programmable and configurable to generate signals to control, for example, the front and rear derailleurs 74 and 76. In one example, the controller can be an Atmel ATmega324PA microcontroller with internal EEPROM memory. The communication module 156 can also be programmable and configurable to send and / or receive signals to control the front and rear derailleurs 76 and 76.For example, the communication module 156 could be a 2.4 GHz Atmel AT86RF231 transceiver, which uses AES encryption and DSS spread spectrum technology, supports 16 channels, and adheres to the IEEE 802.15.4 communication protocol. However, other suitable microcontrollers 160 and communication modules 156 can be used. Additionally, electrical and / or electronic auxiliary devices and components, as is well known in the art, can be used to further improve or enable the function and operation of the microcontroller 160, the communication module 156, and related components.

[0067] In one example, the bicycle control device 100 can include at least one light-emitting diode (LED) 162, which can also be positioned on the PCB 154. The LED 162 can transmit status information to a user or rider regarding the electronic component sets and the function of the gearshift lever assembly 112 or the bicycle control device 100. In this example, the LED 162 is visible through a transparent portion 164 of the seal 152 and a window or opening 166 in the cover 148 of the cavity 146. In one example, the entire seal 152 can be transparent. Alternatively, only the portion 164 of the seal material is configured to allow light to pass through the seal.

[0068] Furthermore, the electronic component sets can include one or more electrical switches 170, 172. When actuated, the electrical switches 170, 172 can cause the controller 160 to perform actions. These actions can include sending and receiving signals, coupling, adjusting, and / or shifting the derailleur and the control device 100, and the like. The switches 170, 172 can generate signals to trigger or elicit an action and / or reaction from various mechanisms of the bicycle 50, such as the front and rear electromechanical derailleurs 74, 76.

[0069] In the present example, the first electrical switch 170 comprises a contact (not shown) on the PCB 154, which is located beneath a spring-loaded coupling switching element 174, also on the PCB. In this example, the first electrical switch 170 is actuated through the seal 152 from outside the cavity 146 and the gearshift lever 132. The cover 148 has a first switching opening 176, where both the cover and the opening are located on the inward-facing side of the gearshift lever 132, i.e., the non-actuating side of the rocker end 138. An actuator 178 is fitted into the first switching opening 176, as shown in Fig. 6, Fig. 10 and Fig. Figure 12 shows that the actuator 178 comprises a button 180, which is received in a hole 182 in the inner wall 130a of the brake lever 102. A spring retainer 184 is held in the first switching opening 176 in the cover 148. A spring 186 extends between the button 180 and the retainer 184 and biases the gearshift lever towards the outer wall 130b of the brake lever 102, as shown in Figure 12. Fig. Figure 10 illustrates this. A user or driver operates the gearshift lever 132 by pressing inwards on the actuating surface, i.e., the outer surface of the rocker end 138, against the preload force of the spring 186. When the driver presses on the rocker end 138, the button 180 eventually contacts the spring retainer 184. Through the seal 152, the spring retainer 184 presses on the clutch switching element 174, which further contacts the contact on the PCB 154 to close and actuate the first electrical switch 170.

[0070] The second electrical switch 172 includes a contact 190 on the PCB 154. The contact 190 can be a clutch switching element or a push-button contact. In the present example, the second electrical switch 172 is also actuated through the seal 152 from outside the cavity 146 and the gearshift lever 132. The cover 148 has a second switching opening 192, where both the cover and the opening are again located on the inward-facing side of the gearshift lever 132, i.e., the non-actuating side of the rocker end 138. A button 194 extends through and is fitted into the second switching opening 192 in the cover 148, as shown in Fig. Figure 6 shows the button 194. The button 194 can be formed integrally as part of the seal 152 or can be attached to the seal material. A user or driver simply operates the second electrical switch 172 by pressing the button 194 towards the cover 148. The button 194, or the underlying material layer of the seal 152, can have a point contact (not shown) at its inner end that presses against the seal 152 to press and close the contact 190, thus operating the second electrical switch 172.

[0071] Keys 180 and 194 function through the material layer of seal 152, thus preserving the integrity of the seal for cavity 146. Different types of electrical switches may be used. The first electrical switch 170 may be used to actuate the bicycle control device 100 on a more frequent and robust basis, such as to initiate gear shifting or a gear change. The second electrical switch 172 may be optional and, in this example, may be smaller and more independent. The second electrical switch 172 may be intended for less frequent use than the first electrical switch 170.In one example, the second electrical switch 172 can be used for operations relating to the coupling of the bicycle control device with a specific bicycle component, such as the front or rear electromechanical derailleur gears 74, 76, or for adjusting the derailleur gears.

[0072] The electronic component sets on PCB 154 and inside cavity 146 are held and sealed within the cavity. The seal 152 lies over PCB 154 and is inserted between the rocker end 138 and the cover 148 of the gearshift lever 132 when the cover is attached to the gearshift lever. With reference to Fig. 10 and Fig. 14. The seal 152 can include a circumferential rib 196 around the sealing material. Likewise, the rocker end 138 can include a groove 198 around the opening into the cavity 146. The rib 196 can be fitted into the groove 198 to create a tight surrounding seal when the cover 148 is secured to the rocker end 138. The material layer of the seal 152 can include raised or thickened regions 200, which can be positioned to coincide with the electrical switches 170, 172 to facilitate effective force transmission from the buttons 180, 194 to the switches. Actuation of the electrical switches 170, 172 sends signals via associated circuits, as is well known, to which the controller 160 is to respond.

[0073] With reference to Fig. 13 and Fig. In the example 14, one or more wires or electrical cables 210 are electrically connected to the electronic component sets of the PCB 154 and routed from the cavity 146 through an opening into the lever arm 140. The wires 210 extend along the interior of the lever arm 140 and are routed around and between the sleeve 144 and the transverse opening 142 at the proximal end 134 of the gearshift lever 132. In the disclosed example, the wires are connected to a power supply, i.e., a self-contained battery unit 212. In the present example, the gearshift lever assembly 112 also includes an accessory bushing body 214, which defines two accessory bushings 216 that are also electrically connected by the wires 210 to the battery unit 212 and the electronic component sets of the PCB 154. In one example, the bushing body 214 can be a single body defining two internal accessory bushings 216 therein.Alternatively, each of the accessory sockets 216 can comprise its own separate body element 214. The wires 210 thus electrically connect the power supply or the battery unit 212 to the accessory sockets 216 and the electronic component sets of the gearshift lever assembly 112.

[0074] The accessory sockets 216 can be connected to the PCB 154 and / or a separate accessory PCB (not shown) inside the accessory socket body 214. The accessory socket body 214, if present, can define one or more than two accessory sockets 216, if desired. Connectors for optional remote actuators, buttons, or switches can be connected to the bicycle control device 100 via the accessory sockets 216. The accessory sockets 216 can then provide power and electrical connection and actuation between the remote actuator(s) and the battery unit 212 and the PCB 154. The accessory sockets 216 can be configured to accept connectors from optional additional and / or remote electrical switches or other devices (not shown), such as optionally placed remote gear shift buttons on the bicycle 50, for the control device 100.If no accessory is connected to the control device 100, the accessory sockets 216 can be closed and / or sealed against moisture and contamination by inserting plugs 218 into the sockets.

[0075] The gearshift lever assembly 112 in the present example is thus a self-contained electrical component of the control device 100. The gearshift lever 132 and the electrical component sets are capable of wirelessly transmitting gearshift control signals to the front and rear derailleurs 74, 76 in response to actuation of the gearshift lever 132. The battery unit 212 and each accessory socket 216 can be connected to the PCB 154 by separate wires 210 using a multi-pin connector. The battery unit 212 and the sockets 216 can either have separate connection points with the PCB 154 or can use a cable assembly that starts with a single wire near the PCB and then branches out into two or more wires. The battery unit 212 and the socket body 214 are each uniquely connected to the housing 104 in accordance with the present disclosure.

[0076] In the present example with reference to Fig. 12, Fig. 15 and Fig. The battery unit 212 comprises a battery box 220 and a battery cover 222. The battery box 220 is received in a recess 224 in the housing 104 and is securely attached to the housing by means of fasteners. In the present example, the battery box 220 is attached to the housing by screws 226, but it could similarly be attached to the housing by means of snap-in features, adhesive, or another suitable device. A conventional and replaceable battery 228, such as a button cell, can be accommodated inside a battery container 230, which is defined by the box 220 and is open to the outside of the housing 104. Alternatively, the battery can be a non-replaceable and / or rechargeable battery. The battery 228 can be configured to provide power to the control module 156, the controller 160, and the remote switches or electrical devices via the accessory sockets 216.The cover 222 is rotatable for installation over the container 230 and the battery 228, and can be reversed to access the battery. The cover 222 may include an elastomeric O-ring or sealing ring 232 around its periphery to create a moisture- and dirt-resistant seal against the box 220 or the housing 104 when installed.

[0077] With reference to Fig. 16. The battery container 230 comprises a positive contact 324 on a peripheral wall 236 of the container and a negative contact 238 in the center of the container on a lower wall 240. Exposed contact sections of the electrical or positive and negative contacts 234, 238 inside the battery container 230 touch the corresponding two terminals of the battery 228. With reference to Fig. The battery box 220 also includes a second cavity 242 on one side opposite the battery container 230, which faces the housing recess 224 when the box is installed. Sections of the electrical contacts 234 and 238 extend through holes inside the box between the battery container 230 and the second cavity 242. Exposed connecting sections of the electrical contacts 234 and 238 are connected to separate wires 210 inside the second cavity 242. These connecting sections can be soldered to join the wires 210 and the contacts 234 and 238, and the wires can then be connected to the PCB 154. Alternatively, the wires 210 can be crimped or otherwise mechanically secured to the exposed sections of the contacts 234 and 238. The positive and negative contacts 234, 238 can be secured to the box via notches in the wall 236 and the base 240 of the battery container 230.Alternatively, the contacts could be attached to the box in a similar way by notches, mechanical fasteners, adhesive or another suitable means.

[0078] During assembly, the second cavity 242, which faces the recess 224 of the housing 104, is filled with an epoxy resin. This resin serves both to secure the contacts 234 and 238 and to hold the wires 210 in place, as well as to create a seal that prevents water and other contaminants from reaching the contacts, the battery 228, the battery holder 230, and the interior of the wires 210. This epoxy seal could similarly be provided by a cover piece attached to the second cavity 242 by plastic welding, fasteners, adhesive, or another suitable means.

[0079] The battery cover 222 can be secured to the housing 220 by conventional mechanical threads. In this example, however, the cover 222 is secured to the housing 220 by a set of tabs 244 or tongues and grooves 246, or other means that interlock when the cover is screwed in. The O-ring 232 is compressed between the cover 222 and the housing 220 or a surface of the casing 104 to provide a secondary seal for the battery housing 230 against water and other contaminants. The battery cover 222 and / or the housing 220 may also include a series of recesses or depressions 250 on the exposed outer surfaces. The outer cover 122 may include projecting bulges (not shown) on the inner side of the cover that are received in these recesses or depressions 250.When the bulging features of the outer cover 122 engage with the recesses or hollows 250, unwanted movement of the battery cover 222 can be prevented or suppressed.

[0080] Fig. Figure 17 shows a cross-section of the assembled control device 100. In the present example, the battery unit 212 is installed in the recess 224 in the housing 104. The wires 210 between the battery unit 212 and the gearshift lever 132 are routed through a first channel 252 in the housing 104 above the recess 224. The battery box 220 includes an upper block section 254 that fits into the first channel 252 to help cover the channel in the assembled control device 100. The block section 254 also helps to align the box 220 during installation in the housing 104.

[0081] In the disclosed example, the housing 104 can be described as having several sides, comprising an inward-facing side, an outward-facing side, a bottom side, and a top side. In the present example, the battery unit 212 is installed on the bottom side of the housing, as shown in Fig. 7, Fig. 8 and Fig. Figure 17 shows that, according to the present disclosure, although the gearshift lever assembly 112 comprises the gearshift lever 132 and electronic component sets, the accessory bushing body 214 and the battery unit 212 as a self-contained assembly, the accessory bushing body can be installed on a different side of the housing 104. Fig. Figures 7 and 18 to 20 show that the accessory socket body 214 is installed in a socket recess 256 on the inward-facing side of the housing 104. A second channel 258 in the housing 104 is located above the socket recess 256 for routing the wires 210 from the socket body 214 to the battery unit 212 and the PCB 254.

[0082] With reference to Fig. 7, Fig. 12 and Fig. A socket cover 260 is detachably attached to the housing 103 to cover the socket recess 256, thereby securing and retaining the socket body 216 within the recess. The socket recess 256 can be shaped to complement the shape of the socket body 216 or the separate socket bodies of the accessory sockets 216. In this example, the accessory sockets 216 are internal sockets with access openings (not shown) located on and accessible from the external surface of the housing 104. The accessory sockets 216 provide an interface between optional remote assemblies of gearshift control buttons and the gearshift control system, which includes the gearshift lever assembly 112. In one example, two or more accessory sockets could be combined into a single assembly, resulting in a single cable assembly consisting of the battery unit 212 and the PCB 154.In the present example, the bushing body 214 is permanently attached to the housing 104 by means of the bushing cover 260, which is fastened to the housing by screws 262. The bushing body 214 could instead be attached to the housing by means of snap-fit ​​features, adhesive, or other suitable means. The bushing body 214 could also not be permanently fixed to the housing, so that the bushing body or the accessory bushings 216 can be removed from the housing when it is not covered by the bushing cover 260.

[0083] Although not shown here, the socket body 214 for each accessory socket 216 can have two cavities comprising an inner cavity located closer to the gearshift control system and separated from an external cavity that defines a plug interface or connector receptacle for receiving a connector for an accessory component. Each plug interface, in use, can be configured to retain a connector of a remote gearshift control button and to electrically connect the connector terminal to one end of a wire or cable assembly terminating at the PCB 154 at the other end. The terminal(s) can extend from the external cavity to the inner cavity for each accessory socket 216 and can be connected to the wire or wires. The inner cavity is filled with epoxy, similar to the second cavity 242 of the battery box.The epoxy can secure the wires in place and create a seal that prevents water and other contaminants from reaching the inner cavity, the cable or wires within it, the plug interface, and the external cavity. Such a seal could instead be provided by molding the socket body or a separate interface piece over the exterior of the wire connections and the socket body.

[0084] With reference to Fig. 7, Fig. 11, Fig. 12, Fig. 13 and Fig. 21, the accessory sockets 216, and in particular the external cavities, can be closed or plugged when not in use by inserting a plug 264 into each of the access openings. The plugs 264 are inserted into the external cavities of the socket body. A seal can be created by means of an elastomeric O-ring (not shown) that is compressed between the outer surface of the plug 264 and the inner wall of the external cavities. The plug seal prevents water and contaminants from reaching the electrical interface and parts inside the socket body 214. The connectors for remote accessories can look and function similarly to the plugs 264, except that each connector would make electrical contact with one or more terminals inside the external cavities. The plugs 264 can include an extension or projection 266, which, respectively,which protrudes from the accessory sockets 216, so that the plugs can be easily grasped and pulled out of the socket body 214 when necessary.

[0085] With reference to Fig. The housing 104 can be formed as shown in figures 17 to 21, such that it has a base section 267 and an extension section 268. The base section 267 can comprise first and second or rearward and forward-facing ends, a downward-facing side 269a, an upward-facing side 269b, an inward-facing side 269c, and an outward-facing side 269d. In the present example, the handlebar clamp 120 is arranged at the first or rearward-facing end. When the control device 100 is mounted on the bicycle handlebar 64, the base section 267 generally extends horizontally, and the extension section 268 extends in front of the base section at the second end and is generally angled upwards from the base section.

[0086] There is an inward-facing side 269c and an outward-facing side 269d, the inward-facing side being closer to the center of the bicycle frame 52 when the housing 104 is mounted on the handlebar 64. In the present example, the remote accessory sockets 216 of the gearshift control are located on the inward-facing side 269c of the base section 267 of the housing 104. However, the sockets could instead be positioned on the outward-facing side 269d or on both sides. Furthermore, in the present example, the battery recess 224 in the housing, and thus the battery box 220, is located on the downward-facing side 269a of the base section 267. One or more electrical wires 210 extend from the upper part of the socket body 214 and between the accessory sockets 216 and the PCB 154.The wires 210 are compressed into the second channel 258 in the housing above the socket recess 256, towards the wires of the battery unit 212, and routed over them. The wires 210 are then routed towards the PCB 154 together with the wires for the battery unit 212. The socket cover 260 may also have a sealing ring or gasket that creates a tight seal between the cover and the housing 104 when installed. When secured to the housing 104, the battery box 220 also has features that secure the wires 210 by compressing them between the battery box and the housing. The battery box 212 also has a guide feature, i.e., the block section 254, that guides the wires from the outside to the inside of the housing 104.

[0087] Fig. 22 and Fig. Figure 23 shows a top view of the housing 104 with the outer cover 122 removed. Fig. Figure 22 shows a chamber 270 in the housing, in which the brake lever 102 is connected to the hydraulic brake system components. The chamber 270 is accessible via a removable chamber cover 272, which is located in Fig. Figure 23 shows that the chamber cover 272 can be secured to the housing 104 by screws 274 or other fasteners, snap-fit ​​connections, adhesive, or other suitable securing devices. Although not described in detail here, the chamber 272 can accommodate and provide access to the components of the control device 100 for maintenance or adjustment. When the outer cover 122 is attached to the housing 104, the chamber cover 272, the socket cover 260, and the battery cover 222 can all be covered, concealed, and protected from the environment.

[0088] With reference to Fig. 17. The hydraulic brake system can generally comprise a housing bore with a master cylinder sleeve 300, which is inserted into the bore and configured to serve as the master cylinder for the brake system. A piston 302 is located in the sleeve 300 and moves relative to it. The piston 302 includes an end 304, which is coupled to the brake lever 102 and is operable by movement of the brake lever, as is known in the art. The master cylinder sleeve 300 is in fluid communication with the chamber 270, which can serve as the brake fluid chamber for the brake system. The chamber 270 can include a drain port 306 and a drain screw 308, which is movable in the drain port, for filling, topping up, or draining the hydraulic fluid of the brake system via the chamber 270.In the present example, a compliant or flexible membrane 310 can be provided over and sealed off the open side of the chamber 270 to provide a defined fluid chamber with a variable volume. The membrane 310 can be positioned between the cover 272 and the open side of the chamber 270, as shown in [Figure]. Fig. 17 illustrated. With reference to Fig. 11 and Fig. 21 The housing 104 of the control device 100 can include a fluid outlet port 312 in conjunction with the master cylinder sleeve 300. When a force is applied to move the brake lever 102, fluid can be driven into the fluid outlet port 312. The housing 104 of the control device can also include an outlet port 314 of the control device, which is in fluid communication with the fluid outlet port 312. A hydraulic brake line 110 can be connected to the outlet port 314 of the control device and to the front or rear brake mechanism 106 or 108 for actuation, as is known in the art. In one example, the chamber cover 272 can be removed to replace or repair the flexible diaphragm 310.

[0089] Fig. 24 and Fig. Figure 25 shows another aspect of the control device 100 according to the disclosure. In the present example, a base plate 280 can be inserted between the cover 148 and the rocker end 138 of the gearshift lever 132 and can be slid in between. Each part can be formed to define a receiving section, such as a recess 282, which clamps an edge of the base plate 280. The base plate 280 can create a contact point between the upper part of the gearshift lever 132 and a contact surface on the inner surface of the front wall 130c of the brake lever, as shown in Fig. Figure 9 shows that the contact surface may include a hump or protrusion 284 positioned to contact the base plate 280. The base plate 280 is essentially clamped between the hump 284 on the inner surface 130c of the brake lever and the recess 282 on the gearshift lever 132. The base plate 280 may be made of a durable material with low-friction properties. For example, the base plate 280 may be made of a different material than the gearshift lever, such as Teflon, and may then be attached to the gearshift lever. The base plate 280 thus allows the gearshift lever 132 to slide laterally and effortlessly with respect to the brake lever 102, preventing jamming and wear.

[0090] In the disclosed control device 100, the inner cavity 146 of the gearshift lever 132 contains the PCB 154 of the gearshift control system and a separate arm cavity 290 extending along the lever arm 140. The lever arm 140 may be open along a forward-facing side oriented towards the front wall 130c of the brake lever. The opening may open into the arm cavity 290, which guides and holds the electrical cable assembly or wires 210 extending between the PCB 154 and the battery unit 212 and the accessory sockets 216. The inner cavity 146 and the arm cavity 290 are joined via an internal hole (not shown) inside the gearshift lever 132. These cavities could alternatively be joined via a notch.The cover 148 is attached to the rocker end 138 of the gearshift lever 132, as described below, to provide a seal that prevents water and other contaminants from reaching the PCB 154. The electrical cable assembly, consisting of one or more independent wires 210, passes through the hole between the inner cavity 146 and the arm cavity 290. The arm cavity 290 is also filled with epoxy during assembly, both to secure the wires 210 in place and to provide a seal that prevents water and other contaminants from accessing the interior of the cable assembly and the wires, the PCB 154, and the inner cavity 146.

[0091] As in Fig.As shown in Figure 14, an epoxy blocking piece 292 can be installed at the location, i.e., the hole between the inner cavity 146 and the arm cavity 290, before applying epoxy to the arm cavity 290. The epoxy blocking piece 292 provides a temporary seal that prevents epoxy from flowing into the circuit board cavity before it hardens. Once the gearshift lever assembly 112 with the brake lever 102 is installed, the epoxy-filled opening along the lever arm 140 faces the front wall 130c of the brake lever, so that it is not readily visible.

[0092] The disclosed control device 100 and the gearshift lever assembly 112 are configured such that the gearshift control system and the battery unit are separate from the accessory sockets, although the electronics are formed as a separate component. This configuration offers several advantages. The battery unit can be located on a different side of the housing than the accessory sockets, allowing the use of a flexible battery cover with a deep recess. Furthermore, the accessory sockets, the battery unit, and the primary gearshift control button assembly are all independently sealed against the ingress of water or contaminants. Thus, moisture and contaminants cannot pass from one subassembly to another within the device. Additionally, no circuit board is exposed when the removable seals for the battery cover and accessory sockets are not present.Therefore, it is not possible for water or dirt to damage the electric gearshift control system when the seals are removed.

[0093] Another advantage is that the electrical cables or wires for the various components are routed around the outside of the housing. This can improve the housing's strength and allows for the complete assembly and installation of the electrical system components before mounting them to the housing. Furthermore, the gearshift control system requires only one circuit board, located within the gearshift lever.
